In January 1997, Gary Barnes posted
a spoof of the Trainspotting
poster to the newsgroup alt.sysadmin.recovery.
I reworked the idea a bit and produced a T-shirt for the group.
The spoof has become quite famous; My original T-shirt webpages were slashdotted on several occasions.
Gaz had a website that outlined the history: http://www.adminspotting.org [WayBack Machine version]
